The window width sets the distance from the setting up point where the 4-
20mA mode starts: 4mA = 0 metering pump pulse, 20mA = max frequency of
the metering pump. The window width depends on many variables: distance
of the injection point, reaction time, chemical product concentration, etc.
With the overdose time alarm one can select a period during which the setpoint must be reached. If the setpoint
is not reached during this period of time, the instrument blocks output operations, including those in mA
(metering pumps), the alarm is displayed as ON and triggers a signalling instrument connected to the alarm
relay.
Maximum Metering is a safety function that ensures metering is completed in
the selected time. The relays of the metering pumps open accordingly. This
function makes it possible to eliminate time limits (continuous metering
according to the selected setpoints) or to select the minutes (up to 999) and
the hours, for instance metering for 999 minutes in 24 hours.

The auxiliary output controls various functions connected to any type of remote On-Off device
controlled by a timer in real time. The AUX output may control a device or appliance thanks to very
accurate programming of minutes/hours/days/weeks. ADVANTAGES: this function makes this
instrument a very versatile control unit not only to measure chemical physical parameters but also for
other functions connected to the system where it is installed.
